It's just another tool you can use for development if you already have a 
recipe for the software you're developing, or are going to write one. As I 
mentioned in another thread, the SDK is mostly there to help developers who 
want to do their application development without the need to interact with the 
tool that builds the entire OS (possibly instead from within an IDE).
